Women's Shoe

The holy grail of off trail running is to provide both stability and flexibility, and the Women's Icebug Zeal does just that. But to make a midsole stable yet soft has so far proven too difficult for P/D teams world-wide. Until now! The development of the Icebug Zeal took more than three years and numerous tests and prototypes to get just right. Upper material is a light yet durable nylon textile, and together with the lacing system it embraces the foot firmly. To further increase the durability the upper fastened with a Stitch-and-turn technique to protect the thread. But it is the midsole construction, and the HGMS2 technology*, that is the true innovation. Zeal provides a stable but soft heel grip, this is the impossible combo, made reality through the moulded midsole cradle on the interior side of the shoe. The midsole not only adds superb fit, it also turns into the reinforcement protecting the foot in serious terrain. The height of the heel cup is slightly reduced at center back in order to reduce the pressure at the Achilles tendon. The medium last is half lined with Quick dry mesh. The torsion and cushioning is in fine balance and together with the low sole profile, the ground control is outstanding. The outsole cleats are positioned so mud doesn’t get stuck, and as if the deep lug pattern doesn't provide traction enough, the RB9X® outsole is the benchmark among “sticky rubbers”! (*Holy Grail Midsole Soft AND Stable – technology)

Who is it for? The trail runner or obstacle course racer looking for a low sole profile and great ground control.
